Comments for what is the best worm to raise in high temperature climate?

I am sorry to inform you that I don't ship to any country other than the continental US.

There are just too many laws and regulations and government restrictions and that's just for one country.

Now compound that with several other countries and it's just a big mess. I really don't think I would get enough orders to justify keeping up on all the customs regulations.

But to answer your question about raising African Nightcrawlers in a hot climate, Yes, they would be a good worm to use.

But you would have to keep them in the shade and make sure they get plenty of moisture and air. If it's really hot then the moisture and air combined would help bring the temperature down in the worm bin quite significantly.

The problem you would have would be the cold nights (if you live in the desert) that would probably kill the African Nightcrawlers.

15°c-25°c (59°F-77°F) is their optimal temperature for maximum performance. So you see, If it gets below this temperature at night for too long, then you can potentially kill them. I would think it is too risky.

On the other hand I think that the Red Wiggler would give the African Nightcrawler some good competition.

Eisenia Fetida are "THE MOST" forgiving composting worm around and are able to adapt to a wide range of temperatures.

I would even say that these would be your best choice of worms for the temperature swings of the desert climates.

Although because of the temperature swings day-in and day-out it would not be an optimal climate for any worm but "Tis better to worm than to not have wormed at all". (I always say :))

So I think you could still have a worm farm, although a bit challenging, but still doable. I think you should probably stay away from "Raising African Nightcrawlers In a Hot Climate / Cold climate".
